I was in the same situation. Then the upgrades came out and I chose the imac 20. I got the 250 Gig HD and RAM boosted to 1Gig. With Apple Care and shipping, it costs $2200. If I went with the dual G5 and a display, (my present monitor is an ancient 17" CRT) the cost would have been well over 3K. I don't need mega power but I needed a display, so for me the imac version B was a no-brainer.
